How to enable PHP OPcode caching for Drupal 8?

Question

I want to enable PHP OPcode caching for Drupal 8 installation. I have the following in Xampp php.ini. However, I still get opcode not enabled. What am I doing wrong??

opcache.enable=1

engine = On
zend_extension=php_opcache.dll


opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

What is your extension_dir value in your php.ini? and where does php_opcache.dll reside? – Muffler

Is there an error message regarding the zend_extension=php_opcache.dll line in the error logs? If not, it is likely that the extension was loaded correctly. – Ferrell

Hello Universe see if this helps :-

• Try to use zend_extension=opcache instead of zend_extension=php_opcache.dll as the former has been deprecated in PHP major version. Check your php.ini file for more details.
• Check if zend.assertions! are enabled.
• I would recommend to go through Opcache issue solved! , which is working fine for most of the cases.
• Restart your Apache.

Answer 3

First of all check your PHP version. Before and after PHP 5.5 things are little bit different. You may refer for difference here http://php.net/manual/en/opcache.installation.php

Also if you are using zend extension then full path of dll is required in below

zend_extension=/your/path/tod/dll/php_opcache.dll

Also make sure to use correct one in terms of threaded or non threaded version.

Open php.ini file. There You have to uncomment this line of code: zend_extension=opcache.so . After that restart lampp/xampp. It works for me.

For Mac Users Go in /Application/XAMPP/etc/php.ini line no.

Change this

;zend_extension=opcache.so

to (remove ;)

zend_extension=opcache.so

Save the file php.ini and restart the server.
